The Centers for Disease Control and Prevention (CDC) and the Texas Department of State Health Services confirmed on July 15 a case of human monkeypox in a U.S. resident who recently traveled from Nigeria to the United States. The man is now hospitalized in Dallas. The CDC has partnered with airlines and state and local health officials to contact airline passengers and others who may have been in contact with the patient on two flights: Lagos, Nigeria, to Atlanta on July 8, upon arrival. July 9; and Atlanta to Dallas on July 9th.
Travelers on flights as well as at U.S. airports are required to wear masks due to the ongoing COVID-19 pandemic Consequently, it is believed the risk of spreading monkeypox through respiratory droplets on other planes and in airports less. Working with airline and state and local health partners, the CDC is examining the potential risks of those who may have close contact with the airline passenger and specific settings.
Monkeypox is a rare but potentially severe viral illness that usually starts with a flu -like illness and inflammation of the lymph nodes and progresses to a widespread rash on the face and body. Most infections last 2-4 weeks. Monkeypox is in the same family of viruses as smallpox but causes a slow infection. In this case, a CDC laboratory test showed that the patient was infected with a type of monkeypox that is commonly found in parts of West Africa, including Nigeria. Infections like this monkeypox can kill almost 1 in 100 people. However, prices can be even higher in people with weakened immune systems.
Prior to the current case, there were at least six reported cases of monkeypox among travelers returning from Nigeria (including cases in the United Kingdom, Israel, and Singapore). This case is unrelated to any of the previous cases. In the United Kingdom, many more cases of monkeypox have occurred in people who have had contact with the cases.
Background on monkeypox in Africa
Experts do not yet know where monkeypox hides in nature, but it is thought that African rodents and small mammals play a part in the spread of the virus to humans and other forest animals such as monkey. People can get monkeypox if they bite or not an animal, prepare wild game, or come into contact with an infected animal or possibly animal products. Monkeypox can also be spread among people through respiratory droplets, or through contact with body fluids, monkeypox diseases, or objects contaminated with fluids or wounds (clothing, bedding, etc.). Human -to -human transmission is thought to occur through multiple respiratory droplets. Respiratory droplets usually cannot travel more than a few feet, so prolonged face -to -face contact is necessary.
Most monkeypox attacks occur in Africa. Apart from Nigeria, outbreaks have also been reported in nine other countries in central and western Africa since 1970. Monkeypox also caused a large outbreak among people in the United States in 2003 after the virus spread from of imported African rodents to prairie dogs.
CDC poxvirus experts have been supporting the investigation and response to monkeypox flare-ups in Nigeria since 2017 when the disease re-emerged in Nigeria after nearly 40 years of non-compliance. reported cases. During 2017, the CDC sent investigators to help the CDC in Nigeria and the National Veterinary Research Institute with tracking the contacts of sick patients, providing diagnostic tests, lab staff in the country to safely test samples from suspected monkeypox cases, providing diagnostic tests and taking small mammals to test for monkeypox (which helps identify which animals carry the disease behavior).
Scientists at CDC labs in Atlanta also provide laboratory tests, including specialist tests to identify people who may have monkeypox and be cured, sequentially to track outbreaks and phylogenetics to determine- an if clusters of cases are relevant. The CDC continues to train Nigerian partners on how to collect wildlife to test which animals carry the virus in nature, helping to improve the country’s ability to track monkeypox cases in humans and interview members. to the community about their interaction with local wildlife. CDC trials are also underway in the Democratic Republic of Congo to examine whether the small-pocket Jynneos vaccine can help protect healthcare workers from contracting an undisclosed monkeypox infection from their patients.
